CURRENT-COLLECTING MECHANISM.

Specification of Letters Patent.

Application filed February 20, 1909. Serial No. 479,072.

Be it known that I, CARL J. EVALD Whx- BOM, a citizen of the UnitedStates, residing 'at Westerville, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in Current-Cbllecting Mechanism, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to terminals for the flexible cables useduponmine locomo-' tives of the gathering type, and has as its object toproduce a hook which can be hung upon atrolley wire and which can bealso used to make running contact with the underside of the trolley wirewhen held in suitable position by the motorman or hip rider. I

In the drawings Figure 1 is a plan view of parts of a mine showing alocomotive approaching the principal entry and drawing current by meansof its conductor cable.

. Fig. 2 is a detail perspective view of'the cable terminal the bookbeing shown in engagement with the under side of a trolley wire.

Locomotives for from the-rooms into trains in the principal entries,which draw their current from fixed conductors by means-of a flexiblecable wound upon a'reel carried by the locomotive, are well known'andcommonly used in mines at the present time. When the locomotive is aboutto leave a prlnclpal entry to run down a side entry and into the roomswhere the coal or other material is being mined, the outer end of thecable is secured to thetrolley wire in the entry. The current flows fromthe trolley wire to the cable, through it to the locomotive motors, andfinds its way back to the generator either through the locomotive wheelsand a ground return on by means of a second conductor in the cable,which. second conductor is connected at its outer end to the rails inthe entry, the rails constituting the return path.

In Fig. 1 of the drawings are shown a principal entry 1 and a side entry2, the tracks 3 in the principal entry and 4 in the side entry, thetrolley wire 5, the gathering locomotive 6 and the conductor cable 7.This cable is wound at one end upon the reel 8 and at the other end isprovided with gathering mine cars 'a hook 9 which is hung upon thetrolley wire 5. I I

When it is desired to run the locomotive dil'OIlrthG position shown inFig. 1 to a position in the principal entry it is frequently foundimpossible under some conditions of use to: run the locomotivesufficiently into the principal entry to make contact between PatentedMay 21, 1912.

the trolley wheel 10 and the trolley wire 5 while the hook is liunguponthe trolley wire. The hook shown in the drawings is especially adaptedto meet this difficulty. When the locomotive has been moved as far outtoward the tracks 3 as is possible with the hook still in engagementwith the trolley wire,the hook is disengaged and is held in contact withthe underside of the trolley wire by the trip-rider or, if it ispossible to do so, by the motor-man, and as the locomotive is propelledpast the turn-out,

the hook is held in sliding contact with the trolley wire until thelocomotive reaches such a position that the trolley pole can be broughtinto position for the wheel to engage the wire.

To make it possible to hold the hook thus in running contact with thewire, a small projecting thumb or lug 11 is formed upon the outer partof the hook by which the concave recess 12 is provided to receive thetrolley wire and to prevent the hook from heavy insulating hose 13 whichserves as a handle for the operator by which he can hold the hook incontact with the trolley wire without danger of shock, and which alsostiffens that part of the cable adjacentthe hook. This stiffening is ofcourse necessary to enable the hook to be held firmly in position. i

What I claim is:

1. A current collecting terminal for a reeled conductor cable comprisinga con ductor hook secured to the free end of the cable, the hook havinga thumb projecting from its outside surface adapted to enable the hookto be pressed upward against a trolley Wire without lateral displacementof the hook. I

2. A. current collecting terminal for a reeled. conduct-or cablecomprising a conductor hook secured to the free end of the cable, thehook being formed to present a ductor hook secured to the free end ofthe cable, the hook being formed to present a concavity in its outersurface adapted to engage a trolley wire from below and prevent lateraldisplacement of the hook with respect to the trolley wire, and aninsulating and stifi'ening hose encircling the cable ad- 5 'jacent saidhook.

5. A manually operable, sliding-contact, current collecting terminal fora reeled conductor'cabie, comprising a conductor hook secured to thefree end of the cable, and a flexible insulating and stifiening hoseencircling the cable adjacent said hook and serving to support the hook.

In testimony whereof I afiix my signature, in presence of two witnesses.
